THE Crown Office is to launch further investigations into the Clutha helicopter crash after admitting relatives of those killed in the tragedy “deserve answers” to a “number of questions” raised by an official report.

After a near two-year wait for answers by families, the Air Accidents Investigation Branch (AAIB) said yesterday that it was “not possible to explain” why pilot David Traill did not follow emergency landing procedures and continued to fly, despite acknowledging five low fuel warnings.

Similarly, the long-awaited report could not shed light on why fuel transfer pumps in the Police Scotland helicopter’s main tank were switched off, which led to its engines failing.

Solicitors representing relatives of the victims said they had been left “angry and frustrated” that there are “still so many questions which may never be answered” following the investigation.

First Minister Nicola Sturgeon said it was “deeply disappointing” the report did not reach a “clearer conclusion” and “raises more questions than it answers” in some areas.

With the Crown Office promising to hold a fatal accident inquiry into the accident, it means families of the ten people who died on 29 November 2013 will have to continue their wait for an explanation of why the crash happened.

The AAIB said it had carried out “extensive analysis” towards the report, but said it faced “limited evidence,” primarily due to the fact the helicopter was not required to be fitted with a flight recorder.

As part of its recommendations, it has called on the regulatory body, the Civil Aviation Authority (CAA), to make it mandatory for all police helicopters to be fitted with equipment to record data, audio and images.

However, the father of a man killed when the helicopter crashed through the roof of the Clutha pub in Glasgow dismissed the AAIB response as “cack-handed” and said similar calls to install flight recorders on emergency services helicopters after a fatal crash in 1998 had not been acted on.

The AAIB report found that although the helicopter had enough fuel on board to complete its journey, 73kg of usable fuel in the main tank did not reach the supply tanks because the transfer pumps were off “for unknown reasons”.

Although Mr Traill acknowledged five low fuel warnings while in charge of the helicopter, it said, he did not follow guidelines which stated he should have landed within ten minutes, instead carrying out three surveillance jobs over Lanarkshire.

The AAIB added the pilot did not complete the emergency shutdown checklist following the first engine failure. The second engine failed 32 seconds later.

Ian O’Prey, whose son Mark was among the victims, said: “The AAIB can only make recommendations. What is the point in that?

“They’ve recommended flight data recorders be installed before, but there’s still aircraft flying around without them, so what good has it done? It’s a bit of a cack-handed effort.”

The CAA issued a statement which said it assisted the AAIB with its investigation and was “studying the report and its recommendations”.

Ollie Dismore, director of operations for the National Police Air Service, said the organisation was “fully supportive” of the recommendations and it would work with the CAA to “fully implement” the new safety regulations, including the fitting of black box recording equipment to new police helicopters.

Andrew Henderson, a partner at Thompsons Solicitors which represents several of the victims’ families, said questions as to why the fuel transfer switches were turned off and the low fuel warnings were not heeded had to be answered.

Ms Sturgeon said: “Our thoughts continue to be with the families and friends of those who lost their lives. I had previously called for this report to be made public as soon as possible and I therefore welcome the fact that has now happened.

“However, it is deeply disappointing that after two years of investigation the report does not reach a clearer conclusion – indeed in some respects, it seems to raise more questions than it answers.

“I therefore share the disappointment of the families that it does not provide the closure they sought and hope that the FAI that the Crown Office has now said will happen as soon as possible, can help the families get the answers they seek.”

A Crown Office spokesman welcomed the report but said it “raises a number of questions for which the families of the victims deserve answers”.

He said: “The Crown will now conduct further investigations into some of the complex issues raised by the AAIB report. We will endeavour to do this as quickly as possible but these matters are challenging and the necessary expertise is restricted to a small number of specialists.

“As this tragedy involves deaths in the course of employment a fatal accident inquiry is mandatory. This will be held as soon as is possible.”
